Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 ESM - Ubuntu 12.04 ESM

Summary:

Several security issues were fixed in OpenLDAP.

Software Description: - openldap: OpenLDAP utilities

Details:

USN-4078-1 fixed several vulnerabilities in openldap. This update provides the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory details:

It was discovered that OpenLDAP incorrectly handled rootDN delegation. A
database administrator could use this issue to request authorization as an
identity from another database, contrary to expectations. (CVE-2019-13057)

It was discovered that OpenLDAP incorrectly handled SASL authentication and
session encryption. After a first SASL bind was completed, it was possible
to obtain access by performing simple binds, contrary to expectations.
(CVE-2019-13565)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 ESM:
slapd 2.4.31-1+nmu2ubuntu8.5+esm1

Ubuntu 12.04 ESM:
slapd 2.4.28-1.1ubuntu4.9

In general, a standard system update will make all the necessary changes.
